One grow, one of your first, if not the, and trying to compare to a dacad later is not a comparison of anything. Do you really think you have the expireance to say that a cob will produce "bigger buds" than a 750DE? You can say cobs do "X"...sort of you have one run under them. But you definitely have no grounds to say HPS does "Y". Stretching and horrible attempts at decade later extrapolations of nothing is poor for LED progress. Stick with only what is. Not what could be.
